Abstract
Description
太陽電池として一般に知られる光起電力(PV)電池は、太陽放射を電気エネルギーに変換するための周知のデバイスである。概して、太陽放射が太陽電池の基板の表面上に衝突し、基板の中に入ることにより、その基板のバルク内に電子‐正孔対が生成される。それらの電子‐正孔対が、基板内のpドープ領域及びnドープ領域に移動することにより、それらのドープ領域の間に電圧差が生じる。それらのドープ領域が、太陽電池上の導電性領域に接続されることにより、その電池から外部回路へと電流が方向付けられる。PV電池が、PVモジュールなどのアレイ内で組み合わされる場合、全てのPV電池から収集される電気エネルギーは特定の電圧及び電流を有する電力を供給できる。
